CuCULLIA VERBA SOI. 



Plate XCVII, fig. 1. 



The larva of G. verbasci is similar in form to that of 

 G. scrojohularidB, but rather larger and thicker when 

 full-grown. The segmental divisions and wrinkles are 

 marked with black interrupted streaks ; the ground- 

 colour is whitish, greenish-white, or bluish-green ; a 

 transverse, equally broad band of yellow, extending to 

 below the spiracles on either side, is seen on the middle 

 of each segment. This character is alone sufficient for 

 its identity ; and although this species varies much in 

 colour and size of markings, yet the design remains 

 in all. 



In rudimentary marked varieties, the transverse 

 central yellow band is often interrupted slightly on the 

 centre of the back, and completely, or partially so, at 

 the sides ; the upper pair of dorsal black spots entire, 

 and never united to those below. In richly marked 

 individuals, the hinder pair of spots becomes elongated 

 and they approach each other, with tails slightly turning 

 upwards ; in others not so confluent, a small twin pair 

 of dots is seen instead on the yellow band in the 

 centre, midway between the large spots. The yellow 

 transverse bands are largely developed on the thoracic 

 segments ; the ordinary spots, dots, and streaks of 

 black on the sides well developed. In some instances 

 the ventral divisions are broadly black, and occasionally 

 the whole surface of the belly is black. Perhaps hardly 

 two larvae could be found exactly alike in the minutiae ; 

 but the transverse band of yellow is the conclusive 

 character, strengthened by the additional one of the 

 black anterior dorsal spots never being united to the 

 posterior pair. (W. B., 1867; E.M.M., October, 

 1867, IV, 117.)
